Test Code: 001958
Specimen Type: Blood
GGT Blood Test Online

Description:

GGT Blood Test (Labcorp)

This test measures Gamma-Glutamyl Transferase (GGT) levels in the blood.  GGT is an enzyme primarily produced by the liver.  GGT is typically increased in cases of disease which cause damage to the liver or bile ducts.  Increased GGT levels are one of the first indicators that the bile ducts are blocked by stones or tumors.  Different conditions which affect the liver can cause increased GGT levels.  For this reason, GGT can be used to screen for liver disease but additional testing will often be necessary to narrow down the specific cause. 

GGT is typically ordered to screen for liver disease or bile duct obstruction.  It is often ordered along with a liver function panel.  People with elevated ALP levels may order a GGT test as a follow-up to help differentiate between liver and bone disease as a cause for increased ALP. 

Turnaround time for the GGT test is typically 1 business day.
